Transverse Waves can be shown via

examples such as water waves, waves

of light that come from the sun, UV waves

and also Infared waves. The difference between

the sun, UV, Infared and water waves, is that the

latter needs matter to pass through matter,

whereas the other three can pass through vacuums

unaffected. These two different waves are called

electromagnetic and transverse matter waves.

This is an example of the many different types of waves

Longitudinal waves can be shown via examples

such as sound or seismic waves. Longitudinal waves

are also known as compression waves, as they sort of

act like the balls of Newton's Cradle, needing to pass

motion along. Another way of describing the way that

Longitudinal waves travel is the poplar game, Chinese

Whispers, as each person takes the message to the next

in line. This is why sound cannot be heard in space, as it

needs air molecules to pass through in order to be heard,

and as space is a vacuum, this does not work. Seismic

waves also work this way, travelling through the Earth's

surface. This is another example of the many types of waves.

Longitudinal Waves

The Two Main types of Waves

Seismic Waves

There are many different types of waves,

but the two main types of waves are

longitudinal and transverse.

Waves

Formulas

Velocity = Wave length / Period

Period = 1 / Frequency

This also works out to be:

Wave length(λ) x Frequency
